Accessories Fittings Sensor Mounting Fittings - Adjustable Adjustable Compression Type Adjustable compression type fittings can be relocated at different positions along the sheath whenever changes in the immersion length are necessary. To relocate an adjustable compression fitting, simply loosen the cap, slide the fitting to the new location and retighten the cap.

It is recommended that lava sealant glands be replaced after each tightening. Tetrafluorethylene (TFE) sealant glands should withstand several relocations before replacement is necessary.

Stainless Steel Adjustable Compression Fitting Except for their sealant glands, these fittings are made entirely of 303 stainless steel. Sealant glands are available in lava, -300 to 1000°F (-184 to 540°C) and TFE, -300 to 500°F (-184 to 260°C). Unless otherwise specified,* TFE sealant glands are provided. Fittings are pressure rated up to 3,000psi depending on temperature and sheath diameter.

Accessories Connectors Many varieties of thermocouple connectors are available from Watlow. Watlow’s broad offering includes benefits such as high impact strength, fast installation and high temperature capabilities. Listed below are the various connectors and systems from which to choose: • Standard thermocouple connectors • Quick-attach thermocouple connectors • High temperature connectors • Three-pole connectors for RTD applications • Miniature thermocouple connectors Watlow’s standard line of connectors are lightweight, rugged and accurate and feature a clamping mechanism that is unique in the industry. This easy-to-use clamping connection will replace traditional screw and wire wrap. This device allows a straight-in application, which squeezes the wire and forms a tight connection assuring a clean, strong signal.

Applications and Technical Data To eliminate measuring errors, all Watlow­connectors are made exclusively of matching metal alloys. If the connector material has different thermal electromagnetic field (EMF) characteristics from the thermocouple or lead wire, a uniform temperature must be maintained across the connector, which is not always easily achievable or practical. If a temperature gradient exists across the connector made with a third metal, unwanted EMFs generate between the thermoelectric materials and the connector extremities causing an error to occur at the thermocouple output. The larger the gradient, the larger the error. In some instances, depending on the calibration, net errors may occur that are even larger than the gradient.

Features and Benefits ASTM color coded • Ensures easy identification Compensated alloys • Provides accuracy in readings Glass-filled thermoplastic • Provides high impact strength Captive cap screws • Ensures a secure connection Connection hardware • Eliminates several components Meets requirements for ASTM E1129 • Ensures adequate pin spacing, dimensions and contact resistance Rated to 425°F (215°C) • Fits high-temperature applications

Accessories Transmitters SERIES 5900 (Isolated) Watlow’s SERIES 5900 temperature transmitter delivers remarkably accurate temperature measurement and improves reliability to reduce downtime and costs. The 5900 SERIES two-wire signal conditioner uses surface mount and digital technology with non-volatile memory. It is designed to fit directly into universal aluminum or universal iron connection heads with a separate mounting kit. The transmitter is programmed using a separate connection cable and an easy-to-use Windows®-based software program. There is no need to use a separate thermocouple/RTD calibrator or individual resistors. The SERIES 5900 is isolated to 1500VAC and features full linearization between temperature sensor input signal and the 4-20mA output signal. Isolated transmitters provide isolation from input to output thus eliminating ground loops and signal integrity. Additional options include insulation resistance monitoring between sensor and ground to prevent inaccurate measurements due to insulation breakdown. Contact Watlow’s customer service department to integrate this transmitter into a Watlow Style AR or AT thermocouple sensor or a Watlow Style RR or RT RTD sensor.
